Product Specification

-
Ordered as TES70393, this is an AS568-393 red PTFE-Encapsulated Silicone 70 Shore A O-Ring supplied with an inside diameter of 23.94 in (608.08 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 24.36 in (618.74 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. Supplementary detail from the product record: ORING 70 Durometer.

Expect good resistance to wide temperature swings, steam, and strong acids and solvents. PTFE-Encapsulated Silicone is widely chosen for a non-contaminating, non-stick sealing surface and excellent recovery across extreme temperature cycling. Service temperature is rated from -75°F (-59.4°C) through 400°F (204.4°C). Applications involving tight-radius dynamic flexing or installation over sharp edges call for a different compound.

It sees regular use in pharmaceutical manufacturing, cryogenic and high-temperature equipment, and food and beverage processing.

Reference part number TES70393 when ordering; the item is sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
